who have answers, please run this code one time so you can understand because i tried many thing but not worked for me

Thank You for helping me... :)

The whole code is here.

Console.WriteLine(endl<<"2:T-NAWAJ"<<endl;??
COnsole.WriteLine("/n"+"NAWAJ"+"/n"); it is true?

how to give line break in C# in one line?

Ohh Sorry

public void mon()
{
Console.WriteLine("mon mat cse che eee L me1270 ");
Console.WriteLine("/n,/n");
Console.WriteLine(" JAHID AJHER MORSHAD DABROTO LIAJE & SULTAN ");

return 0;
}

It is true? if its then its giving redline under return 0

its a C++ Code i m trying to convert it in C#

OK thanks

Have seen already but not to clear about these one's

i am trying that how to i move a circle around screen like diamod shape

Mehdi Gholam thanks alot Sir

thnx

1)What is BaudRate and why we use 9600 not other?
2)If parity is for error checking then why we set Parity.None?
3)What is Databits?
4)What is Handshake do?
5)
Collapse | Copy Code
this.serialPort.WriteLine("AT" + (char)(13));// why we set char 13?

6)this.serialPort.WriteLine("AT+CMGF=1" + (char)(13));//also here char 13?
7)this.serialPort.WriteLine(">" + messages + (char)(26));//why we set char 26 here?

question in\\ after coding see

its not working its give error"Does not contain a definition for loadports and no extension methods" :(

its not working its give error"Does not contain a definition for loadports and no extension methods" :(

Thank you :)its work for me...

Thank you so much :)

Hm thnx ED i will try

here SMS class
namespace SMS
{
class SmsClass
{
SerialPort serialPort;
public SmsClass(string comPort)
{
this.serialPort = new SerialPort();
this.serialPort.PortName = comPort;
this.serialPort.BaudRate = 9600;
this.serialPort.Parity = Parity.None;
this.serialPort.DataBits = 8;
this.serialPort.StopBits = StopBits.One;
this.serialPort.Handshake = Handshake.RequestToSend;
this.serialPort.DtrEnable = true;
this.serialPort.RtsEnable = true;

}
public bool sendSms(string cellNo, string sms)
{
string messages = null;
messages = sms;
if (this.serialPort.IsOpen == true)
{
try
{
this.serialPort.NewLine = System.Environment.NewLine;
this.serialPort.WriteLine("AT" + (char)(13));
Thread.Sleep(4);
this.serialPort.WriteLine("AT+CMGF=1" + (char)(13));
Thread.Sleep(5);
this.serialPort.WriteLine("AT+CMGS=\"" + cellNo + "\"");
Thread.Sleep(10);
this.serialPort.WriteLine(">" + messages + (char)(26));
}
catch (Exception ex)
{
//MessageBox.Show(ex.Source);
}
return true;
}
else
return false;
}

public void Opens()
{
if (this.serialPort.IsOpen == false)
{
this.serialPort.Open();
}
}
public void Closes()
{
if (this.serialPort.IsOpen == true)
{
this.serialPort.Close();
}
}
}
}

i want that when i close form2 so form1 close automatically its not closed when i closed Form2?? help me plz
thnx

Thank you so much for helping me... :)

Thank you so much its work for me...:)

Thanx ED but this code sent msg only One Number(1st number of the loop) not other numbers
any idea what to do...?
